STOPPER FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 703,735, dated July 1,1902.

Application filed December 31, 1901- Serial No. 87,864:- (No model.)

stoppers for bottles, especially to stoppersfor bottles for containingand administering volatile liquids.

The object of the invention is to provide a tight, can be opened andclosed ,easily and rapidly, and when so opened permits the internalpressure in the bottle to eject the;1iq-' uid in a jet or stream withwhich the stopper does not interfere.

In the accompanying drawing a vertical sectional view of the stopper isshown.

An externally-threaded sleeve a (shown in dotted lines) is secured on abottle-neck 12. (Also shown indotted lines.)

The metal block A is provided in its bottom with an internally-threadedrecess B, into which the sleeve (1 can be screwed, a packing-ring W,made of vulcanized fiber or a gelatinous mass, for the purpose offorming a tight joint, preferably placed on the upper edge of thebottle-neck b and sleeve a.

The block A is provided in its upper end with a recess 0, screw-threadedat its upper part,which recess can be closed bya threaded cap D, whichcan be screwed into the upper end of said recess. A threaded valve stemE is screwed through a threaded central hole F in said cap D and at itslower end carries a valve-head G, having a recess in its under side, andin this recess a packing H is secured. This valve can seat on the upperend of a tube J, extending from the bottom ofthe recess 0 downto therecess Band bottle-neck b, the upper end of the tube J being flush withthe bottom of the recess G. A washer I, of suitable packing material,such as vulcanized fiber, extends to the sides of the recess 0 and ismounted on the stern E, directly above the valve-head G, which washerforms a tight joint, so as to prevent the liquid from working up intothe upper recess in the block A. This washer I rests upon a smallermetallic washer d, which in fromthe bottle.

turn rests upon the shoulder formed by the upper edge of the valve-headG. The valvestem E has a longitudinal fine bore 01, extending from itsupper end to the valve G and communicating with a duct (2, extending tothe side of the valve. A disk L for turning the valve-stem J' axially isformed on the stem above the cap D. A cap M, having a capillary aperture0 in its upper closed end, is screwed on the threaded upper end part Jof the stern J above the disk L. Ordinarily-the'valve G is screwed downso as to :close the upper end of the tube J, thus prenew and improvedstopper which is simple" in construction, closes the bottle absolutelyventing the escape of the volatile liquid When such liquid is to beu'sed,'the disk L is turned to raise the valve The volatile liquid isnow forcedby the pressure in the bottle through the tube J and throughthe duct 6 and bore d into the cap M, from which it emerges as aifinejet through the aperture 0. This jet 'canbe'stopped at any time byscrewing down the valve G sufliciently to cause it to seat on the upperend of the tube J.

Having described my invention, what I :claim' as new, and desire tosecure by Letters Patent, is-

The combination with a bottle, of a threaded sleeve applied on theoutside of the neck of the bottle, a packing-ring 0n the upper end ofthe bottle-neck, a block provided in its bottom with aninternally-threaded recess into which the sleeve on the bottle-neck canbe screwed, said block also having in its upper 'part a recess providedwith a bottom opening, a cap on said block, a screw-stem mounted to turnin said cap, a head on the lower end of said screw, and provided on itsunder side with a recess, a. yielding packing secured in said recess inthe under side of the head; which yielding packing is adapted to closethe bottom opening -in the-top recess formed in the block, thescrew-stem having a duct extending from the side of the valvehead to theupper end of the screw-stem, substantially as set forth.

Signed at Woodridge, inthe county of Bergen and State of New Jersey,this 15th day of November, A. D. 1901.
